Possible Interop unlock found for the Nokia Lumia 800

It seems OEM apps with their high level of access and poor security is a gift that keeps on giving, at least to the hacker community.

The latest is the Nokia Network Setup App, which has a vulnerability which could allow an Interop Unlock, which gives full access to the device at a root level, to be achieved by deploying a specially crafted provisioning file.

The vulnerability and associated exploit was discovered by Heathcliff74 on XDA-Developers is is still in testing.

Update: Nanapho.jp reports that after the exploit has been made public Nokia has unpublished Nokia Network Setup from Marketplace. The XAP can still be downloaded, but can now no longer be installed.
